Nice video. Can you explain why when you had 1/x=1/√5-√3 you multiplied by √5+√3 up and down, I thought as an equality, we should multiply by the same number both sides. I am a little confused
Yes, in this case we multiply by the conjugate both above and below to eliminate the radicals from the denominator, the new fraction that we add does not affect our problem because this fraction is equal to 1. Thank you for your comment. Hope I've helped my friend. 👍🏻🤜🏼🤛🏼
Wow thats Cool
Thank you so much my friend! 👍🏻

Thanks for the explanation. I totally omitted the fact that the fractions are equal to 1. Makes sense now. Thank you very much
